EXTENSION-BRACKET.

SPECIFICATION forming part of Letters Patent NO. 476,446, dated June 7,1892.

Application tiled November 9, 1891. Serial No.4l1,242. (No model.)

To all whom, t may concern;

Be it known that I, JOHN G. BROTHWELL, of Torrington, in the county ofLitchfield and State of Connecticut, have invented a new and usefulImprovement in Extension-Brackets, of which the following is aspecification.

My invention relates to an improvement in extension-brackets, and moreparticularly in extension-brackets designed for the support of polesfrom which drapery is hung.

The object is to provide a simple and strong bracket, which may be adjusted with great facility, and one that may be manufactured at a lowinitial cost.

A practical embodiment of my invention is represented in theaccompanying drawings, in which- Figure l represents a bracket invertical section, showing in full lines its position when partiallyextended and in dotted lines its position when fully extended and whenfully closed. Fig. 2 is a top plan view, and Fig. 3 is an enlarged viewin detail of the interlocking end of the sliding member.

I In the form which I prefer and which I have herein illustrated thebracket is composed of two pieces only, exclusive of the binding-screwfor holding the pole in place. The stationary member consists of a flatstrip of metal or other 'suitable material having a horizontal portion Aand an inclined brace portion A', the extremities of the horizontal andbrace portions being turned at an angle forming a tiange a and ct',respectively, adapted to bear against the support to which the bracketis to be secured and provided with perforations ft2 for the reception ofa screw or other suitable fastening. The horizontal portion A isprovided with an elongated slot d3 for the reception of the end of thesliding member of the bracket. The sliding' memberof the bracket is alsoformed of a strip of metal or other suitable material, and has astraight shank portion B bent at its outer end into U-shaped form,asshown at h,tor the reception of the pole or rod for the support of thedrapery, and at its inner end it is formed T-shaped, as shown at b',Fig. 3, by cutting slots b2 inwardly from its opposite edges toward thecenter. The shank b3 of the T portion is bent substantially atrightangles to the portion B and is adapted to enter and slide within theslot as in the partA of the stationarymember. The shank h3 is of suchlength that when the part B rests in proximity to the part A with theshank b3 in the slot a3 the head of the T portion will rest underneaththe part A and in proximity thereto, thereby locking the sliding memberto the stationary member. At the point where the horizontal portion A ofthe 6o stationary member is turned downwardly to form the brace port-ionAaportionof the metal, preferably at the center ofthe strip, is struckup, forming alug or stud d4, adapted to enter some oneof theseries ofperforations bformed in the portion B of the sliding member, and therebyprevent a lateral displacement of the sliding member relatively to thestationary member. The weight of the pole or perforated supporting-rodresting in the U-shaped 7o portion b of the sliding member will tend tolift the inner end of the sliding member and to depress the shankportion B onto the stud or lug a4. As the inner end cf the said slidingmember is securely locked by the T head against upward displacement, andas the stud a4 securely locks the said member against lateraldisplacement, it follows that the sliding portion will be firmly held inits position until the outer end is lifted, which is not liable to 8ohappen except intentionally.

To lock the pole or drapery-supporting rod in position, I provide aset-screw C, seatedin a threaded perforation in the outer branch of theU-shaped portion of the sliding' member, 85 and for the purpose ofpresenting a neat appearance I find it desirable to provide the setscrewC with an ornamental head c, which may be of concave form, as hereinrepresented, or of any other well-known form suitable for 9o thatpurpose.

The parts may be assembled by turning the sliding member at right anglesto the stationary member and slipping its head downwardly through theslot a3 and then swinging it laterally until it rests in a position inthe general direction of the part A.

To adj ust the bracket inwardly or outwardly, it is only necessary tolift the sliding member upwardly out of engagement with the lug a4 rooand then slide it along the slot a3, either inwardly or outwardly, thedesired distan ce and then allow it to drop in position to receive thelug a4 into one of the perforations Dl.

While I find it desirable as a matter of economy in manufacture tostrike the lug et* up from the metal of the stationary member it isobvious that it might be formed separately and secured thereto, or theperforations might be formed in the stationary memberand several lugssubstituted Ifor the perforations in the sliding member, which wouldamount to a mere reversal of parts. It is also obvious that the T-head bmightbe formed separately and secured to the end of the sliding memberinstead of being formed integral therewith.

Vhat I claim is The extension-bracketcomprisingtwostrips of metal, theone bent into shape to form the horizontal and brace portions of thebracket and having its ends turned to torni iianges for the reception ofthe fastenings and having an elongated slot in its horizontalportion andthe other having one of its ends bent to form a seat for the thing to besuspended and its other end T-shaped and turned downwardly to passthrough the said slot and engage the under side of the horizontalportion of the other strip, one of the pieces having a lug struck upfrom its surface and the other having recesses formed in it to receivethe lug, substantially as set forth.
